Publication number: 20140334107Abstract: A portable electronic device including a temperature sensor embedded in a die is provided. To process temperature measurements the portable electronic device includes a processor circuit coupled to the temperature sensor, the processor circuit configured to read a measurement from the temperature sensor when an integrated circuit in the die is inactive. Furthermore, a memory circuit coupled to the processor circuit and the temperature sensor stores a temperature gradient provided by the temperature sensor. A Printed Circuit Board for use in a portable electronic device as above is also provided. A method for performing thermal control in a portable electronic device as above is also provided.Type: ApplicationFiled: May 9, 2013Publication date: November 13, 2014Applicant: Apple Inc.Inventors: Amaury J. HERESZTYN, Ihtesham H. CHOWDHURY, Keith COX

Patent number: 8768530Abstract: A predefined mathematical relationship that is stored in the memory of a computing system is accessed, wherein the relationship refers to temperatures of a number of points in the system, wherein the points together define a zone. The mathematical relationship yields a representative temperature for the zone. Temperature data from sensors in the system is obtained and applied to thermal models, to estimate the temperatures of at least some of the points that define the zone. The representative temperature for the zone is computed using the estimated temperatures as input to the mathematical relationship. A decision is then made on whether or not to change a power consuming activity limit in the system, based on the computed representative temperature. Other embodiments are also described and claimed.Type: GrantFiled: August 23, 2010Date of Patent: July 1, 2014Assignee: Apple Inc.Inventors: Frank Faqiu Liang, Jay S. Nigen, Amaury J. Heresztyn, Keith Cox

Publication number: 20140085911Abstract: The described embodiments relate generally to thermal management and more particularly to a method and apparatus for providing thermal insulation from relatively small heat sources in small form factor electronic devices. An insulator layer can be placed between a small heat source and an exterior surface of the device, such as a cover glass layer. In one embodiment, a graphite layer can also be included between the cover glass layer and the insulator layer to spread any transmitted heat across the cover glass layer.Type: ApplicationFiled: July 11, 2013Publication date: March 27, 2014Inventors: Lian Zhang, Amaury J. Heresztyn, Frank F. Liang

Publication number: 20140003083Abstract: A flat-panel display (such as a liquid crystal display) includes one or more features that reduce temperature changes in an array of light valves disposed on a substrate. In particular, heat generated in a light source and/or electronics is conducted away from the light values. For example, a light-source holder, which contains the light source, may include holes that increase the thermal resistance between the light source and the substrate. Alternatively, the light-source holder may include a material having a thermal conductivity that is higher than that of stainless steel. In addition, the flat-panel display may include materials and/or a geometry that increases the thermal resistance along a direction in a plane of the substrate. By reducing temperature changes in the flat-panel display, these features can reduce or eliminate color changes and other visual artifacts that can degrade the quality of displayed images.Type: ApplicationFiled: June 27, 2012Publication date: January 2, 2014Applicant: APPLE INC.Inventors: Ihtesham H. Chowdhury, Frank F. Liang, Amaury J. Heresztyn, Jeremy C. Franklin, Benjamin M. Rappoport, Derek W. Wright

Patent number: 8360718Abstract: A method and apparatus to improve air flow in an air circulating fan assembly by forming an inlet opening in a fan assembly. A static air pressure profile is calculated along a top portion of the fan assembly configured to operate in an enclosure. The shape of a section of the inlet opening in the top portion of the fan assembly is changed based on a pressure contour of the calculated static air pressure profile. The method is repeated iteratively one or more times using an inlet opening changed by a previously calculated static air pressure profile when calculating a subsequent static air pressure profile. The inlet opening is positioned in the top surface of the fan assembly so that the centroid of the inlet opening is laterally offset with respect to the rotational axis of an impeller in the fan assembly.Type: GrantFiled: January 29, 2010Date of Patent: January 29, 2013Assignee: Apple Inc.Inventors: Jesse T. Dybenko, Frank Liang, Amaury J. Heresztyn, Brett W. Degner, Thomas W. Wilson, Jr., Peteris K. Augenbergs, Connor R. Duke

Publication number: 20120162751Abstract: An optical coating includes multiple layers of different materials and thicknesses and is disposed proximate a transparent display cover for an electronic device display. The optical coating transmits most visible light, reflects most non-visible light and substantially absorbs blackbody radiation generated from within the electronic device. The optical coating can be readily removable from the electronic device display either alone or in combination with a removable transparent display cover. The multiple layers comprise two or more materials having alternating low and high indices of refraction, and can include 36 or more layers, each having a thickness ranging from 10 to 400 nanometers. The arrangement and thicknesses of the layers are designed based upon the thickness and optical properties of the transparent display cover.Type: ApplicationFiled: December 23, 2010Publication date: June 28, 2012Applicant: APPLE INC.Inventors: Frank F. Liang, Phillip L. Mort, Amaury J. Heresztyn, Jay S. Nigen, Simon Prakash, John P. Ternus

Publication number: 20120162095Abstract: An internal optical coating includes multiple layers of different materials and thicknesses and is disposed between a transparent display cover and a visual display unit for an electronic device display. The optical coating transmits most visible light, reflects most non-visible light and substantially absorbs blackbody radiation generated from within the electronic device. The multiple layers comprise two or more materials having alternating low and high indices of refraction, and can include 36 or more layers, each having a thickness ranging from 10 to 400 nanometers. The arrangement and thicknesses of the layers are designed based upon the thickness and optical properties of the transparent display cover. The internal optical coating can also be specially formulated to replace a typical internal anti-reflective coating proximate the visual display unit.Type: ApplicationFiled: February 15, 2011Publication date: June 28, 2012Applicant: APPLE INC.Inventors: Frank F. Liang, Amaury J. Heresztyn, Phillip L. Mort, Carl Peterson, Benjamin M. Rappoport, John P. Ternus
